Thanks TechTeacher. I use brass rod that I get from a local hardware store that carries the K&M Metals hobby display. They have many diameters in 2 or 3 ft lengths as well as brass tubes and small sheets.

Thanks guys, yes the hinges are about 5/16” at the thickest point, set in 1/8” or so then shaped. I’m looking for some clock chain to add for protection. Lowes didn’t have any with small enough links that would match the box.
